  • a freely rota table roller 20 extends between each pair of members 18.
  • a pair of parallel rollers 22 extend side-by-side in the channel section 14.
  • the rollers 22 are interconnected by gearing located in a box 23 at the rear end of the vehicle 28, so as to simultaneously rotate at the same rate but in opposite directions to each other.
  • a respective cover member 24 of flexible sheet material is provided, mounted around each roller 22, extending over the respective rollers 20 and fixed to the respective side wall 26 of the pick-up truck 28 by conventional clips 30.
  • Spring urging arrangements 32 are provided extending respectively between the frame 12 and each side wall 26.
  • the arrangements 32 each comprise two pairs of pivotted arms 34, with a compressed spring 36 interconnecting the pivotal connections.
  • the arms 34 are arranged to respectively point outwardly, and downwardly or upwardly away from the spring 36.
  • Each arrangement 38 comprises a sprung roller 40 upon which a further cover member 42 of flexible sheet material is fitted.
  • the free end of the cover member 42 is mountable to the respective end of the load carrying area 16 again by clips 30, and roller 40 urges materials thereonto.
  • the assembly 10 is fitted on to the load carrying area 16 of the truck 28 as described. If the truck 28 is empty or only carrying a low load, the rollers 22 are activated to wind in a maximum amount of the cover member 24 to provide a low cover as shown in Fig. 1. Winding in of the cover member 24 urges the arrangements 32 to a flat condition by compressing the spring 36.
